Intel releases details on the graphics capabilities tucked inside the 4th Core CPU generation (aka "Haswell")-- now with three graphics tiers named Intel HD 5000, Iris and Iris Pro.
The previous Core chip generation ships with two flavours of graphics, Intel HD 4000 and HD 3000.
With Haswell, Ultrabooks carrying 15W U-series CPUs get the updated HD 5000 graphics. Laptops using 28W U-series chips get Iris, which Intel claims is up to x2 faster than HD Graphics.
The more powerful H- and R-series laptop chips (47-55W) pack Iris Pro graphics with embedded DRAM. M- and K-series laptop CPUs also get the Iris Pro option.
Intel HD 5000, Iris and Iris Pro leverage on Direct X 11.1, OpenGL 4 and OpenCL 1.2 technologies, with "enhanced" 4K output and a 3-screen collage mode.
